4.29. Result
An estimate of the value of some property generated by a known procedure
[OM]
4.30. Sample
A representative subset of the physical entity on which an observation is made.
4.31. Sensor
An entity capable of observing a phenomenon and returning an observed value. Type of observation procedure that provides the estimated value of an observed property at its output.
Note: A sensor uses a combination of physical, chemical or biological means in order to estimate the underlying observed property. At the end of the measuring chain electronic devices often
produce signals to be processed.
4.32. Sensor Model
In line with traditional definitions of the remote sensing community, a sensor model is a type of Location Model that allows one to georegister or co-register observations from a sensor
particularly remote sensors.
4.33. Sensor Data
List of digital values produced by a sensor that represents estimated values of one or more observed properties of one or more features.
Note: Sensor data is usually available in the form of data streams or computer files.
4.34. Sensor-Related Data List of digital values produced by a sensor that contains ancillary information that is not
directly related to the value of observed properties Example: sensor status, quality of measure, quality of service, battery life, etc. Such data
can be sent in the same data stream with measured values and when measured is sometimes indistinguishable from sensor data.
4.35. Sensor Platform
An entity to which can be attached sensors or other platforms. A platform has an associated local coordinate reference frame that can be referenced relative to an external coordinate reference
frame and to which the reference frames of attached sensors and platforms can be referenced.
4.36. Transducer
An entity that receives a signal as input and generates a modified signal as output. Includes detectors, actuators, and filters.
4.37. Value
A member of the value-space of a datatype. A value may use one of a variety of scales including nominal, ordinal, ratio and interval, spatial and temporal. Primitive datatypes may be combined to
form aggregate datatypes with aggregate values, including vectors, tensors and images
